Finding and Replacing Text
This article applies to Visual Studio 2015. If you're looking for Visual Studio 2017 documentation, use the version selector at the top left. We recommend upgrading to Visual Studio 2017. Download it here.
You can find and replace text in the Visual Studio code editor, and certain text-based output windows such as the Find Results windows, using the Find and Replace control or Find/Replace in Files. You can also search and replace in some designer windows, such as the XAML designer and the Windows Forms designer, and tool windows
You can scope searches to the current document, the current solution, or a custom set of folders. You can also specify a set of file name extensions for multi-file searches. You can customize search syntax by using .NET regular expressions.
To find and replace regular expressions, see Using Regular Expressions in Visual Studio.
The Find/Command box is still available as a toolbar control, but is no longer visible by default. You can display the Find/Command box by choosing Add or Remove Buttons on the Standard toolbar and then choosing Find. For more information, see Find/Command Box.
Find and Replace control
The Find and Replace control appears in the upper right corner of the code editor window. The Find and Replace control immediately highlights every occurrence of the given search string in the current document. You can navigate from one occurrence to another by choosing the Find Next button or the Find Previous button on the search control.
You can access replacement options by choosing the button next to the Find text box. To make one replacement at a time, choose the Replace Next button next to the Replace text box. To replace all matches, choose the Replace All button.
To change the highlight color for matches, choose the Tools menu, select Options, and then choose Environment, and select Fonts and Colors. In the Show settings for list, select Text Editor, and then in the Display items list, select Find Highlight (Extension).
Searching Tool Windows
You can use the Find control in code or text windows, such as Output windows, and Find Results windows, by choosing Find and Replace on the Edit menu or (CTRL+F).
A version of the Find control is also available in some tool windows. For example, you can now filter the list of controls in the Toolbox window by entering text in the search box. Other tool windows that now allow you to search their contents include Solution Explorer, the Properties window, and Team Explorer, among others.
Find/Replace in Files
Find/Replace in Files works like the Find and Replace control, except that you can define a scope for your search. Not only can you search the current open file in the editor, but you can also search all open documents, the entire solution, the current project, and selected folder sets. You can also search by file name extension. To access the Find/Replace in Files dialog box, choose Find and Replace on the Edit menu (or CTRL+SHIFT+F).
When you choose Find All, a Find Results window opens and lists the matches for your search. Selecting a result in the list displays the associated file and highlights the match. If the file is not already open for editing, it is opened in a preview tab in the right side of the tab well. You can use the Find control to search through the Find Results list.
Creating Custom Search Folder Sets
You can define a search scope by choosing the Choose Search Folders button (it looks like …) next to the Look in box. In the Choose Search Folders dialog box, you can specify a set of folders in which to search, and you can save the specification so that you can reuse it later. You can specify folders on a remote machine only if you have mapped its drive to the local machine.
Creating Custom Component Sets
You can define component sets as your search scope by choosing the Edit Custom Component Set button next to the Look in box. You can specify installed .NET or COM components, Visual Studio projects that are included in your solution, or any assembly or type library (.dll, .tlb, .olb, .exe, or .ocx). To search references, select the Look in references box.
